Expansive clay is a problematic soil when a structure is constructed on it. Recently many researchers used industrial ‎waste in soil stabilization as low cost materials and to save the environment. In this regard, an attempt is made to ‎evaluate the use of Marble Waste Powder (MWP) to stabilize expansive soil. Soil samples were mixed with different ‎proportions of MWP 0%, 10%, 15 % and 20% by dry weight. Sieve analysis, Atterberg's limits, Standard Proctor, ‎Unconfined Compression Strength (UCT) and Free Swell (FS) tests were performed on natural and stabilized soils. ‎The tests results revealed that the soil plasticity (i.e. liquid limit and plasticity index), free swell index (FSI) and ‎optimum moisture content reduced significantly with the addition of MWP, while the maximum dry density and ‎UCS of the stabilized soil greatly increased with increase in MWP amount. It’s concluded that the use of MWP will ‎improve the properties of expansive soil and it is beneficial for economical and environmental considerations.‎
